DRIVING MECHANISM FOR CENTRIFUGAL LlQUID-SEPARATORS.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed May 31,1905. Serial No. 263,024.

To all whom it may concern.-

Be it known that I, THOMAS W. MORGAN, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Driving Mechanism for Centrifugal Liquid-Separators, of which the following is a specification.

Myinventienrelates to driving mechanism for centrifugal liquid-separators; and the object of my invention is to provide a combination of spiral gear-wheels and spiral pinions which will cause a reat multiplication of revolutions, which will be most effective and steady in use with a minimum of wear and liability to breakage, and whose elements will so interact as to reduce the pressure within the step-bearings, thus lessening the friction therein. This object I have attained by the mechanism which is hereinafter shown and described, being illustrated by the accompanying drawing, which represents a vertical section of a casing contalnin my improved form of compound gearing or actuating a centrifugal liquid-sop arator.

The casin r is mounted on a base a: and is supplied with an elastic collar-bearin s for the reception of the spindle t of a centrifugal liquid-separator bowl. Asideless boxing g is contained within said casing-frame r a: and has perforations in its up er plate for the reception of bearings c an in its lower plate for the reception of the step-bearings n. Adjusting-nuts p, fitted with sleeve-nuts z, are placer in the lower ends of the step-bearings 'n. The n pen ends of these adj usting-nuts p are furnis ed with hemispherical bosses, on which rest similar hemispherical bosses on the lower ends of the shafts a,d, and h. The upper ends of the shafts a and (1 rotate within the bearings 0, while the shaft it passes through an o ening in the upper plate of the boxing q, SLIM its upper end rotates in a hearing to, fitted in a bracket of the casing r. The bearing to has the adjusting-nut oiitted therein, having on its lower end a hemispherical boss which contacts with a similar hemis iherical bosson the upper end of the shaft A two-part horizontal shaft Z a is rotatable in bearings in the upper part of the casin r and is fitted with an exterior crank m. large bevel-gear 7c is mounted on the shaft Z, and its teeth mtermesh with the teeth of a small bevel gear 21, mounted on the u per end of the shaft h. A spiral gear-whee f is mounted on the lower end of the shaft h, and its teeth intermesh with those of the spiral pinion e, mounted on the shaft (1. A spiral gearwheel 0 is mounted on the shaft d, and its teeth engage those of a s iral pinion b on the shaft a. The upper en of the shaft ois constructed of a sultable shape to enter an opening in the lower end of the spindle t, while the stud y engages the sides of a slot in said s indie. When the gear-whcei k is rotated y means of the crank -m,it imparts r0- tation to the car i, shaft h, and spiral gear f, the latter multiplying the revolutions of the spiral inion e and spiral gear-wheel c on the shaft 5 and the spiral gear-wheel 0 again multiplying the revolutions of the spiral Jinion (3 and shaft (1 with the engaged spindle t of the centrifugal liquid-separator bowl.

It will be observed that the directions of rotation of the spiral gear-wheels f and c are reversed in relation to each other. The result of this reversal in the engagement of said spiral gear-wheels with the spiral pinions c and b, respectively, is when they are in rapid rotation to exercise a lifting stress upon the shaft (1 and its attached superincumbent spindle t of the separator-bowl, which greatly relieves the pressure upon and friction between the surfaces of the o )posing bosses in the step-bearing. The ad ed result is obtained of greater ease of operation and a steadier motion of revolution. The use of spiral ear also creates greater wearing-surfaces a ong the contact ed es of the teeth of each, thus preventing rapir wear and making the caring longer lived.

I aving described my invention, what I claim as new, and desire to secure by Letters Patent, is

l A driving mechanism for centrifugai liq ind-separators, com )rising a removable boxing, bearings in said oxing, a rotatable shaft, a spiral gear-wheel mounted thereon, a rotatable shaft, a spiral pinion thereon intermeshing with said spiral gear-wheel, a spiral gear-wheel on said spiral-pinion shaft, a retatable shaft, a s iral pinion thereon intermeshing with the est-mentioned spiral gearwheel, and a driven spindle actuated by said last-mentioned shaft.

2. A driving mechanism for centrifugal liquid-separators, com rising an external easing, a removable hol ow boxing therein, antifrietion-bearings in said boxing, shafts mounted in said bearings, a crank, intermeshing spiral gearing on said shafts arranged to drive a spindle, and a driven spindle.

3. A driving mechanism for centrifugal liquid-separators, comprising a rotatable shaft, a bevel-gear mounted thereon, a boxing in said casing provided with bearings, a rotatable shaft in said boxing having a bevel gearwheel intermeshing with said first-mentioned bevel gear-wheel, a spiral gear-wheel mounted on said bevel-gear shaft, a rotatable shaft, a spiral pinion thereon interineshing with said spiral gear-wheel, a spiral gear-wheel on said spiral-pinion shaft, a rotatable shaft, a s )iral pinion thereon intermeshim with the lastmentioned spiral gear-whel, and a driven spindle actuated by said last mentioned shaft.

4. A driving mechanism for centrifugal liqind-separators, comprising a suitable boxing, a driven spindle, rotatable shafts in said boxin intermeshing spiral gear-wheels and spira pinions on said shafts s0 arranged that the directions of revolution of both the gearwheels and the pinions are respectively reversed in relation to each other producing a lifting stress by reason of their coo )eration upon the driven spindle, substantially as described.
